The Hitchhiker's Guide to the Galaxy was a science fiction comedy series, originally broadcast on radio, and that was later adapted into a series of novels. The Hitchhiker's Guide to the Galaxy was created by Douglas Adams, and proved extremely popular; eventually culminating into a Hollywood movie.
In 1984, the National Science Foundation - a U.S. government agency - planned the creation of a computer network. Designed in 1985, and launched in 1986, NSFNET would become one of the most important computer networks ever created. NSFNET used the TCP/IP protocol system - that was developed by DARPA - and became the primarily 'backbone' network of the Internet in the 1980's.
In 1985, Ed Krol was one of the network engineers who helped build NSFNET. It became apparent to Ed Krol that no one had published a guide to the Internet, and that information was "thin on the ground" for a history of how the Internet was created and what is the Internet. Therefore, in 1987, with funding from the National Science Foundation, Ed Krol published the 'Hitchhiker's Guide to the Internet'.
